MACHINE FOR MAKING HAY-TIES.

SPECIFICATION forming part of Letters Patent No. 590,338, dated September 21, 1897; Application filed September/14, 1896. Serial No. 605,746. (No model.)

To vill whom, it may concern.-

Be it known that 1, JOHN A. SCHARF, a citizen of .the United States, residing at Richwood, in the county of Union and State of Ohio, have invented a new and useful Improvement in Machines for Making Hay-Ties, of which the following is a specification.

The object of my invention is to provide a machine for making wire hay-ties used in tying hay-bales and is composed of the parts described in the following specification and the accompanying drawings, in which Figure 1 is an elevation; Fig. 2, an elevation of the opposite side, and Fig. 3 is a plan view of the complete machine. Fig. 4 is a detail elevation of a part of the main wheel and accompanying parts. Fig. 5 is a detail of the clamp m. Fig. 6 is a detail plan view of the parts shown in Fig. 4:. Fig. 7 is an edge View of a part of the wheel (Z and pinion s. Fig. 8 is a detail of the hub of the main wheel, showing cams and followers. Fig. 9 is an edge view of a part of the main wheel, showing shears n. Fig. 10 is a detail side view of parts shown in Fig. 0.

Similarletters refer to similar parts throughout the several views.

The main frame of the machine is composed of the three longitu dinal bars a, a, and a" and cross-bars b and band the bars 0 and 0. Between the bars a and a the wheel (Z is mounted on the shaft 61, resting in the boxes cl, with the belt-pulley e on the end of the shaft d. The rim of the wheel d is formed of the web f and flange f, a segment of which is stopped off on one side of the wheel from end to end of the rack g on the face of the web f. On the side of the web f on which the rack g is located is the arm h, with the point h and the axis h" passing through the web f and terminating in the latch Attached to the web f and surrounding the axis 7t and 0011- necting at one end to it is the spiral spring j, which holds the arm 71, in a normal position, except when drawn over by drawing the wire from the spool.

The operation of the parts above described in conjunction with the other working parts is as follows: A strand of wire 7c is passed through the clamp k and the eye Z of the guide Z", pivoted into the bars a and a at Z and held in the normal position by the spring m. From the eye Z thewire it passes through the clamp on and over the notched end of the bar 0 to the point where the shears it cut it off.

As the wheel (1 rotates, the cam 0, as shown in Fig. 4, operates the lever 0, which is connected by the rod 0" to the crank p, the opposite end of which connects by the rod 19 to the arm 19, which causes the looper q to make a half-revolution, bending the end of I the wire around the twister q into the jaws of the clamp m, which shuts tightly onto the wire 70 by the operation of the rod q, 0011- nected from the clamp m to one end of the crank 0', from the other end of which the rod r connects to the lever 0', which is operated by the cam 'r'. lVhen the wire 7V" is thus secured into the clamp m, the twister qf makes several rotations by the rack g engaging with the pinion s. The pinion s is provided with the collar 5, having the fiat side .9, which is designed to rest in contact with the edge of the flange f and retain the twister with its point up, except when the rack 9 comes into contact with the pinion s, at which point the flange f stops off from end to end of the rack g to permit the flat side of the collar 5 to disengage and rotate freely.

The rack g'is of proper length to give the pinion 5 any desirable number of complete revolutions, so that when it leaves the pinion s the twister will stand with the point up and the flat surface s of the collar .9 will be toward the flange f and in position to engage with it. By the rotation of the twister q a loop is twisted on the end of the wire 70, and as the wheel d continues to rotate the arm It moves upward and the point It passes closely in front of the twister g and passes into the loop formed in the wire and raises it from the twister q and moves upward and rearward as the wheel (1 continues to revolve, drawing the wire 1" rom the spool through the clamps L and m, which-have now been released by their respective operating-cams. As the wheel cl continues to rotate, the arm h turns on its axis h", so that the tension of the wire 70 keeps the end on which the point h is located held toward the direction of the pinion 3, and when diametrically opposite the pinion s the latch 43 engages with the catch it, operated by the spring a, at which point the shears a pass by the pinion s and cut off the wire 70 by the strike 11' causing the shears to 1 close while passing that point. After passing the strike at the shears n are thrown open and ready for the next passage by the spring or. The tie is now made and cut oi, the cut end falling into one of the holders t. As the wheel 01 continues its rotation the arm it passes the holder at that end of the machine which catches the loop end of the tie and the point it passes out of the loop, and as it passes the trip a the catch a is thrown over and the latch 2' is released, when the spiral spring jinstantly throws it over and it locks into the catch t, as in Fig. 4, and the arm h and point h are in normal position.

ready to pick the next loop from the point of the twister q. Immediately after passing the twister q and raising the loop the catcht strikes the trip-pin n, which releases the latch i and permits the arm h to gradually make its half-rotation on its axis as made necessary in pulling the wire from the feed-spool.

\Vith each revolution of the wheel d a complete tie is made and deposited in the holders t I The function of the guide Z, as above described, is to hold the wire 7c in proper position, and it is pivoted at the two points 1" to allow its end Z to be lifted upward as the arm h approaches the highest point on the wheel d in making its revolution. After the arm h passes the twister q the clamp m opens and releases the wire, allowing it to have a direct pullfrom the clamp 74; to the arm it, thus avoiding a short bend, which would otherwise be made at the clamp m as the arm approached the highest point on the wheel d. After the arm h passes the highest point and descends toward the opposite side the wire lowers to a horizontal position and the spring on forces the guide Z down to its normal position. The function of the clamp 70 is to hold the wire 70 in tension while being drawn through it as the wheel cl revolves and, when drawn to the point where the shears n cut otf the tie, to hold it absolutely tight. This is done by the cam '10, operating the lever w, and the rod 10', attached to one end of the crank 70. p

The clamp k is held in normal tension by the spring 00 acting against the crank 7:. All of the various parts as described above are so located in their relative positions that each one acts in proper time to perform its part of the entire process in making a complete tie. If it should be necessary or desirable to make ties of shorter lengths, the web f of the wheel 01 may be widened at the point where the arm his located and several holes provided on a radial line for the axis h" and diiferent and longer arms h be made to set into any of the holes provided for making shorter ties. The method of imparting power to the shaft (1 may be by the belt-pulley e or by a hand-crank attached in its place.- In place of the pulley e a large cog-wheel may be attached, engaging with a pinion on a counter- V shaft provided with a belt-pulley.

As described in the foregoing'specification and shown in the accompanying drawings, I claim as my invention and desire to have secured by Letters Patent 1. In a hay-tie machine, the combination of a main frame composed of longitudinal and cross bars, and mounted thereon a main shaft carrying a main wheel provided with a flanged rim, a rack-on said rim engaging with and operating a pinion mounted on an axis with its end pointed and bent at a right angle forming a twister, a looper for bending a wire around said twister forming a loop, cranks, rods,and cams on the main shaft for operating said looper, an arm on the main wheel with latch-catches and springs operating therewith to retain in proper position a finger for lifting the loop of the tie from the twister and drawing its proper length from the feed-spool, a shears on the rim of the main wheel operated by a strike on the main frame for cutting the tie at the proper point, a strike on the main frame for releasing. the loop-lifter and allowing it to assume its normal position, a spring- 7 guide for guiding thewire, a clamp in front of the twister with crank, rod, and cam on main shaft for operating said clamp, a tension-clamp at the end of the main frame with means for operating it from the main shaft by cam, rod, and crank, and a spring operating with said crank for keeping the wire in normal tension, substantially as shown and described for purposes stated.
